When the Gaang settled down for the night, Natasha just laid there and looked up at the sky.
What's next? Natasha thought, we've gotten through the first and second episodes, the third and the fourth, and... I think "The King of Omashu" is next?
"Mmr?" went Momo.
"Momo, what is so interesting about me?" Natasha whispered.
"Mmr."
Natasha groaned. "Come here,"
Momo jumped on Natasha's chest and laid there.
"He really likes you for some reason," said a childish voice.
"Aang?" Natasha said, "Why are you awake?"
"I can't stop thinking," Aang said, "about that other Airbender."
Natasha picked up Momo in her arms and sat up.
"I mean, what if we left them on Kyoshi Island? How old are they? Did they get frozen in an iceberg, too? What if-"
"Aang," Natasha said. Tell him. Tell him! "I'm... sure that you'll see them again. Maybe you'll actually get to meet her- or him.
Aang sighed. "I remember when I was little, like, most of my little kid life, there was this girl that was a little older than me, and she hung out with me a lot. I don't know why, but she seemed to always be with me."
"What else?" Natasha asked.
"Well, when I was seven, she just suddenly disappeared. I don't know where she went, but I think it was another Air Temple." Aang scratched his head, trying to remember. "I remember eavesdropping on these people talking, saying something about my 'sister', and I couldn't be distracted, since I was the Avatar."
"Are you saying you think this Airbender is that girl?" Natasha asked.
"It turned out, that girl was actually my sister. And, yes, I think the Airbender is her."
Natasha thought for a moment. "You'll see her again," she said, "I promise. Now, get some sleep. We're headed to Omashu tomorrow, right?"
Aang got confused. "How did you know that?"
Natasha smiled. "I just know. Goodnight."
"Uh... okay... goodnight," Aang said.
Natasha laid down, confused.
What if I am his sister?
